A disk cartridge housing an optical disk is provided, a rotation wheel is housed rotatably in a cartridge body and which houses the disk and has formed therein a second opening corresponding to a first opening and through which the housed disk is exposed to outside, and a pair of shutter plates which are pivoted in conjunction with the rotation of the rotation wheel to uncover the first and second openings when the latter coincide with each other. The rotation wheel has formed at the front side thereof, at which the disk cartridge is first inserted into a disk recorder and/or player, a to-be-operated portion in which a shutter releasing portion of the disk recorder and/or player is engaged, and the to-be-operated portion is formed from a concavity opening the front side of the disk cartridge at which the latter is first inserted into the disk recorder and/or player.

A slidable rotation of the inner shell to the outer shell causes slidable rotation of the shutter members to open or close the opening portion of the outer shell, and the disk cartridge is inserted into an insertion opening of the disk drive apparatus so that the disk-shaped recording medium is mounted on the disk table to be used. An discrimination groove opened at least to an insertion direction side to the insertion opening of the disk drive apparatus for performing discrimination from another type of the disk cartridge is formed on the outer shell.

A disc drive unit capable of simply performing an opening and closing driving of shutters by rotation of an inner rotor of a disc cartridge using the inner rotor is provided. A disc drive unit is constituted so as to open and close shutters (9, 10) by rotationally driving a partial gear (27) of the inner rotor (4) by a rack portion (74) of a rack member (71) slidably driving it relative to a disc cartridge (1).

A disk cartridge does not require a plate supporter for holding a chucking plate on an upper shell. In this disk cartridge, a chucking plate for chucking a disk on a turntable, driven by a spindle motor, is placed on the middle of the disk so the chucking plate is vertically movable together with the disk. The disk cartridge further includes a peripheral cylindrical rib which is not in contact with the disk and is configured to limit movement of the chucking plate in the direction of its diameter while permitting the vertical movement of the chucking plate. The peripheral cylindrical rib is molded integral with the lower surface of the upper shell.
摘要:
The present invention is related to a disc cartridge in which an optical disc, an inner shell and shutter members are housed in a main cartridge body unit, formed by abutting and combining upper and lower shells and in which the inner shell is run in rotation to cause the shutter members to open or close an aperture provided in the main cartridge body unit. The inner shell is formed by a resin molding portion comprised of a first molded portion for forming the inner shell and a second molded portion connected to the first molded portion. The second molded portion is provided at a position forming the aperture in the inner shell and is connected to the first molded portion through a flanged thin-walled section. The inner shell is formed by severing the second molded portion and the flanged thin-walled section.
摘要:
A method for producing an inner shell used for a disc cartridge in which an optical disc, an inner shell and shutter members are housed in a main cartridge body unit. The inner shell provided in the main cartridge body unit includes a first molded portion, provided with an aperture, a second molded portion having a resin injection port and molded at a position where the aperture is formed, and a flanged thin-walled section connecting the first and second molded portions to each other. The method includes the steps of injecting molten resin into a cavity defined by a fixed metal die and a movable metal die for molding the first molded portion, the second molded portion, and the flanged thin-walled section, and severing the flanged thin-walled section by a punch provided to the movable metal die before the molten resin injected into the cavity is cooled and solidified.

摘要:
A disk cartridge in which a pair of shutter members can be opened and closed smoothly and reliably, and a dust-proof property and an airtightness of a large opening portion can be increased by reducing a space between a pair of shutter members and a cartridge housing as much as possible. The disk cartridge comprises a cartridge housing in which a disk compartment is formed-between an upper shell and a middle shell by overlapping the upper shell, the middle shell and the lower shell and the middle shell is supported by the upper shell and the lower shell so as to become freely rotatable, an optical disk rotatably stored within the disk compartment and a pair of shutter members attached to the middle shell in such a manner that they can be moved in the plane direction on the same plane. A shutter opening and closing mechanism for opening and closing opening portions by moving the pair of shutter members based rotation of the middle shell.

A disk cartridge does not require a plate supporter for holding a chucking plate on an upper shell. In this disk cartridge, a chucking plate (5) for chucking a disk (4) on a turntable (41) driven by a spindle motor is not supported by an upper shell (2) but placed on the middle of the disk (4) so as to be vertically movable together with the disk (4), and a peripheral cylindrical rib (6) being not in contact with the disk (4) and functioning as positioning means for limiting movement of the chucking plate (5) in the direction of its diameter while permitting the vertical movement of the chucking plate (5) is molded integral with the lower surface of the upper shell (2).
